| 1 | An adaptive attitude algorithm based on a current statistical model for maneuvering acceleration显示文摘A current statistical model for maneuvering acceleration using an adaptive extended Kalman filter(CS-MAEKF) algorithm is proposed to solve problems existing in conventional extended Kalman filters such as large estimation error and divergent tendencies in the presence of continuous maneuvering acceleration. A membership function is introduced in this algorithm to adaptively modify the upper and lower limits of loitering vehicles' maneuvering acceleration and for realtime adjustment of maneuvering acceleration variance. This allows the algorithm to have superior static and dynamic performance for loitering vehicles undergoing different maneuvers. Digital simulations and dynamic flight testing show that the yaw angle accuracy of the algorithm is 30% better than conventional algorithms, and pitch and roll angle calculation precision is improved by 60%.The mean square deviation of heading and attitude angle error during dynamic flight is less than3.05°. Experimental results show that CS-MAEKF meets the application requirements of miniature loitering vehicles. | Wang Menglong Wang Hua | 2017 | Chinese Journal of Aeronautics2017,30,1: | 11 |
| 2 | De Novo Design of Polymeric Carrier to Photothermally Release Singlet Oxygen for Hypoxic Tumor Treatment显示文摘Intratumoral hypoxia extremely limits the clinic applications of photodynamic therapy(PDT).Endoperoxides allow thermally releasing singlet oxygen(1O_(2))in a defned quantity and ofer promising opportunities for oxygen-independent PDT treatment of hypoxic tumors.However,previous composite systems by combining endoperoxides with photothermal reagents may result in unpredicted side efects and potential harmful impacts during therapy in vivo.Herein,we de novo design an all-in-one polymer carrier,which can photothermally release 1O_(2).Te strategy has been demonstrated to efectively enhance the production of 1O_(2) and realize the photodamage in vitro,especially in hypoxic environment.Additionally,the polymer carrier accumulates into tumor afer intravenous injection via the enhanced permeation and retention efects and accelerates the oxygen-independent generation of 1O_(2) in tumors.Te oxidative damage results in good inhibitory efect on tumor growth.Realization of the strategy in vivo paves a new way to construct photothermal-triggered oxygen-independent therapeutic platform for clinical applications. | Tianci Huang Menglong Zhao Qi Yu Zheng Feng Mingjuan Xie Shujuan Liu Kenneth Yin Zhang Qiang Zhao Wei Huang | 2019 | Research2019,,1: | 6 |
| 3 | Multiple sulfur and oxygen isotope compositions in Beijing aerosol显示文摘Multiple sulfur isotopes(32S, 33 S, 34 S, 36S) and oxygen isotopes(16O, 18O) in Beijing aerosols were measured with MAT-253 isotope mass spectrometer. The δ34S values of Beijing aerosol samples range from 1.68‰ to 12.57‰ with an average value of 5.86‰, indicating that the major sulfur source is from direct emission during coal combustion. The δ18O values vary from 5.29‰ to 9.02‰ with an average value of 5.17‰, revealing that the sulfate in Beijing aerosols is mainly composed of the secondary sulfate. The main heterogeneous oxidation of SO2 in atmosphere is related to H2O2 in July and August, whereas H2O2 oxidation and Fe3+ catalytic oxidation with SO2 exist simultaneously in September and October. Remarkable sulfur isotope mass-independent fractionation effect is found in Beijing aerosols, which is commonly attributed to the photochemical oxidation of SO2 in the stratosphere. In addition, thermochemical reactions of sulfur-bearing compounds might be also a source of sulfur isotope anomalies based on the correlation between ?33S and CAPE. | GUO ZhaoBing WU MengLong LIU FengLing WEI Ying LI DongFang | 2014 | Science China Earth Sciences2014,57,11: | 5 |
| 4 | Lectin receptor kinase OsLecRK-S.7 is required for pollen development and male fertility显示文摘Pollen grains are covered by exine that protects the pollen from stress and facilitates pollination.Here we isolated a male sterile mutant s13283 in rice exhibiting aborted pollen with abnormal exine and defective aperture.The mutant gene encodes a novel plasma membrane-localized legume-lectin receptor kinase that we named OsLecRK-S.7.OsLecRK-S.7 was expressed at different levels in all tested tissues and throughout anther development.In vitro kinase assay showed OsLecRK-S.7 capable of autophosporylation.Mutation in s13283(E560K)and mutation of the conserved ATP binding site(K418E)both knocked out the kinase activity.Mass spectrometry showed Thr376,Ser378,Thr386,Thr403,and Thr657 to be the autophosphorylation sites.Mutation of individual autophosphorylation site affected the in vitro kinase activity to different degrees,but did not abolish the gene function in fertility complementation.oslecrk-s.7 mutant plant overexpressing OsLecRK-S.7 recovered male fertility but showed severe growth retardation with reduced number of tillers,and these phenotypes were abolished by E560K or K418E mutation.The results indicated that OsLecRK-S.7 was a key regulator of pollen development. | Xiaoqun Peng Menglong Wang Yiqi Li Wei Yan Zhenyi Chang Zhufeng Chen Chunjue Xu Chengwei Yang Xing Wang Deng Jianxin Wu Xiaoyan Tang | 2020 | Journal of Integrative Plant Biology2020,62,8: | 4 |
| 5 | Identification of late-stage pollen-specific promoters for construction of pollen-inactivation system in rice显示文摘Large-scale production of male sterile seeds can be achieved by introducing a fertility-restoration gene linked with a pollen-killer gene into a recessive male sterile mutant.We attempted to construct this system in rice by using a late-stage pollen-specific(LSP)promoter driving the expression of maizeα-amylase gene ZM-AA1.To obtain such promoters in rice,we conducted comparative RNA-seq analysis of mature pollen with meiosis anther,and compared this with the transcriptomic data of various tissues in the Rice Expression Database,resulting in 269 candidate LSP genes.Initial test of nine LSP genes showed that only the most active OsLSP3 promoter could drive ZM-AA1 to disrupt pollen.We then analyzed an additional 22 LSP genes and found 12 genes stronger than OsLSP3 in late-stage anthers.The promoters of OsLSP5 and OsLSP6 showing higher expression than OsLSP3 at stages 11 and 12 could drive ZM-AA1 to inactivate pollen,while the promoter of OsLSP4 showing higher expression at stage 12 only could not drive ZM-AA1 to disrupt pollen,suggesting that strong promoter activity at stage 11 was critical for pollen inactivation.The strong pollen-specific promoters identified in this study provided valuable tools for genetic engineering of rice male sterile system for hybrid rice production. | Menglong Wang Wei Yan Xiaoqun Peng Zhufeng Chen Chunjue Xu Jianxin Wu Xing Wang Deng Xiaoyan Tang | 2020 | Journal of Integrative Plant Biology2020,62,8: | 4 |
| 6 | GDSL esterase/lipases OsGELP34 and OsGELP110/OsGELP115 are essential for rice pollen development显示文摘Pollen exine contains complex biopolymers of aliphatic lipids and phenolics.Abnormal development of pollen exine often leads to plant sterility.Molecular mechanisms regulating exine formation have been studied extensively but remain ambiguous.Here we report the analyses of three GDSL esterase/lipase protein genes,OsGELP34,OsGELP110,and OsGELP115,for rice exine for-mation.OsGELP34 was identified by cloning of a male sterile mutant gene.OsGELP34 encodes an endoplasmic reticulum protein and was mainly expressed in anthers during pollen exine formation.osgelp34 mutant displayed abnormal exine and altered expression of a number of key genes required for pollen development.OsGELP110 was previously identified as a gene differentially expressed in meiotic anthers.OsGELP110 was most homologous to OsGELP115,and the two genes showed similar gene expression patterns.Both OsGELP110 and OsGELP115 proteins were localized in peroxisomes.Individual knockout of OsGELP110 and OsGELP115 did not affect the plant fertility,but double knockout of both genes altered the exine structure and rendered the plant male sterile.OsGELP34 is distant from OsGELP110 and OsGELP115 in sequence,and osgelp34 and osgelp110/osgelp115 mutants were different in anther morphology despite both were male sterile.These results suggested that OsGELP34 and OsGELP110/OsGELP115 catalyze different compounds for pollen exine development. | Huihui Zhang Menglong Wang Yiqi Li Wei Yan Zhenyi Chang Haoling Ni Zhufeng Chen Jianxin Wu Chunjue Xu Xing Wang Deng Xiaoyan Tang | 2020 | Journal of Integrative Plant Biology2020,62,10: | 4 |
| 7 | Covalent organic frameworks-incorporated thin film composite membranes prepared by interfacial polymerization for efficient CO_(2) separation显示文摘Thin film composite(TFC)membranes with nanofillers additives for CO_(2)separation show promising applications in energy and environment-related fields.However,the poor compatibility between nanofillers and polymers in TFC membranes is the main problem.In this work,covalent organic frameworks(COFs,TpPa-1)with rich ANHA groups were incorporated into polyamide(PA)segment via in situ interfacial polymerization to prepare defect-free TFC membranes for CO_(2)/N_(2)separation.The formed covalent bonds between TpPa-1 and PA strengthen the interaction between nanofillers and polymers,thereby enhancing compatibility.Besides,the incorporated COFs disturb the rigid structure of the PA layer,and provide fast CO_(2)transfer channels.The incorporated COFs also increase the content of effective carriers,which enhances the CO_(2)facilitated transport.Consequently,in CO_(2)/N_(2)mixed gas separation test,the optimal TFC(TpPa_(0.025)-PIP-TMC/m PSf)membrane exhibits high CO_(2)permeance of 854 GPU and high CO_(2)/N_(2)selectivity of 148 at 0.15 MPa,CO_(2)permeance of 456 GPU(gas permeation unit)and CO_(2)/N_(2)selectivity of 92 at 0.5 MPa.In addition,the Tp Pa_(0.025)-PIP-TMC/m PSf membrane also achieves high permselectivty in CO_(2)/CH_(4)mixed gas separation test.Finally,the optimal TFC membrane showes good stability in the simulated flue gas test,revealing the application potential for CO_(2)capture from flue gas. | Haoqing Xu Wenyan Feng Menglong Sheng Ye Yuan Bo Wang Jixiao Wang Zhi Wang | 2022 | Chinese Journal of Chemical Engineering2022,35,3: | 3 |
| 8 | A distributed spatial computing prototype system in grid environment显示文摘Digital Earth has been a hot topic and research trend since it was proposed,and Digital China has drawn much attention in China.As a key technique to implement Digital China,grid is an excellent and promising concept to construct a dynamic,inter-domain and distributed computing environment.It is appropriate to process geographic information across dispersed computing resources in networks effectively and cooperatively.A distributed spatial computing prototype system is designed and implemented with the Globus Toolkit.Several important aspects are discussed in detail.The architecture is proposed according to the characteristics of grid firstly,and then the spatial resource query and access interfaces are designed for heterogeneous data sources.An open-up hierarchical architecture for resource discovery and management is represented to detect spatial and computing resources in grid.A standard spatial job management mechanism is implemented by grid service for convenient use.In addition,the control mechanism of spatial datasets access is developed based on GSI.The prototype system utilizes the Globus Toolkit to implement a common distributed spatial computing framework,and it reveals the spatial computing ability of grid to support Digital China. | WU Lun,YAN MengLong,GAO Yong,YANG ZhenZhen,ZHAO Yong & CHEN Bin Institute of Remote Sensing and Geographic Information System,Peking University,Beijing 100871,China | 2010 | Science China(Technological Sciences)2010,53,S1: | 3 |
| 9 | CaMKIIα-driven,phosphatase-checked postsynaptic plasticity via phase separation显示文摘Ca^(2+)/calmodulin-dependent kinase Ila(CaMKIla)is essential for synaptic plasticity and learning by decoding synaptic Ca^(2+)oscillations.Despite decades of extensive research,new mechanisms underlying CaMKIIa's function in synapses are still being discovered.Here,we discover that Shank3 is a specific binding partner for autoinhibited CaMKIla.We demonstrate that Shank3 and GluN2B,via combined actions of Ca^(2+)and phosphatases,reciprocally bind to CaMKIla.Under basal condition,CaMKIla is recruited to the Shank3 subcompartment of postsynaptic density(PSD)via phase separation.Rise of Ca^(2+)concentration induces GluN2Bmediated recruitment of active CaMKIla and formation of the CaMKIIa/GluN2B/PSD-95 condensates,which are autonomously dispersed upon Ca^(2+)removal.Protein phosphatases control the Ca^(2+)-dependent shuttling of CaMKIla between the two PSD subcompartme nts and PSD condensate formation.Activation of CaMKIla further enlarges the PSD assembly and in duces structural LTP.Thus,Ca^(2+)-induced and phosphatase-checked shuttling of CaMKIla between distinct PSD nano-domains can regulate phase separation-mediated PSD assembly and synaptic plasticity. | Qixu Caic Menglong Zeng Xiandeng Wu Haowei Wu Yumeng Zhan Ruijun Tian Mingjie Zhang | 2021 | Cell Research2021,31,1: | 3 |
| 10 | BIK1 cooperates with BAK1 to regulate constitutive immunity and cell death in Arabidopsiss显示文摘In Arabidopsis,both the membrane-anchored receptor-like kinase(RLK) BAK1 and the receptor-like cytoplasmic kinase(RLCK) BIK1 are important mediators of transmembrane signal transduction that regulate plant development and immunity.However,little attention has been paid to their genetic association.This study found the bak1 bik1 double mutant of Arabidopsis displayed a severe dwarfism phenotype due to constitutive immunity and cell death in developing plants.These data suggest that BIK1 cooperates with BAK1 to regulate constitutive immunity and cell death. | Jun Liu Sufen Chen Lijuan Chen Qi Zhou Menglong Wang Dongru Feng Jian-Feng Li Jinfa Wang Hong-Bin Wang Bing Liu | 2017 | Journal of Integrative Plant Biology2017,59,4: | 2 |
| 11 | Sodium-rich volcanic rocks and their relationships with iron deposits in the Aqishan-Yamansu belt of Eastern Tianshan,NW China显示文摘The volcanic rocks hosting the iron deposits in the Aqishan–Yamansu metallogenic belt are sodium-rich.The geochronology,petrography,and geochemistry of minerals and sodium-rich rocks as well as the relationship between these rocks and the iron deposits are studied.Geochemically,the ore-hosting volcanic rocks are sodiumrich(the averages of Na2O and Na2O/K2O are 4.31 wt.%and 8.56,respectively)and belong to the calc-alkaline series.They are enriched in LREEs and LILEs(Ba,U,K,and Sr),but depleted in HFSEs(Nb,Ta,and Ti).SHRIMP zircon U–Pb dating of the crystal tuff in the Aqishan Formation and the dacite in the Tugutu Bulak Formation yields ages of 337.52.3 Ma(n?15,MSWD?0.85)and 313.03.3 Ma(n?13,MSWD?0.74),respectively,indicating that the sodium-rich volcanic rocks formed from the early–late Carboniferous.Electron microprobe data from plagioclases demonstrate that albites and/or oligoclases were formed in the basic–intermediate–acid volcanic rocks.Two stages of albitization are identified,and the latter is likely attributed to the dissolution of iron in the Aqishan–Yamansu belt.The sodium-rich volcanic rocks probably formed by the interaction between volcanic lava and seawater after volcanoes erupted on the seafloor;meanwhile,the albites formed by element substitution in a low-metamorphic environment.The spatiotemporal coupling relationship between sodium-rich volcanic rocks and iron deposits in the Aqishan–Yamansu belt is favorable.Iron dissolved from the dark minerals of basic–intermediate volcanic rocks through sodium metasomatism is one of the material sources for the iron deposits. | Zhiyuan Sun WangJingbin Yuwang Wang Lingli Long Zhaohua Luo Xiaohua Deng Qitao Hu Menglong Wang | 2020 | Geoscience Frontiers2020,11,2: | 2 |

| 16 | Finite Element Analysis and Experiment on Viscous Warm Pressure Bulging of AZ31B Magnesium Alloy显示文摘Aiming at overcoming the low plasticity of magnesium alloy at room temperature, we researched viscous warm pressure bulging(VWPB) of AZ31B magnesium alloy based on the excellent thermal stability of viscous medium under the warm forming condition. The potential improvements of plastic deformation ability and forming quality of AZ31B magnesium alloy are expected with the aid of thermal characteristics of viscous medium. During bulging process the velocity field variation and pressure stress field distribution of viscous medium are observed at different temperatures through which the effect of temperature on the mechanical property of viscous medium and AZ31B magnesium alloy are analyzed. The results show that the formability of AZ31B magnesium alloy increases first and then decreases as the temperature increases and it is the best at 200 ℃. On the other hand, the viscous medium which can build non-uniform pressure stress field also exhibits a good flow property at elevated temperature, and it is helpful to improving the formability of AZ31B magnesium alloy. | 高铁军 ZHANG Wenzhuo XU Menglong WANG Zhongjin | 2017 | Journal of Wuhan University of Technology(Materials Science)2017,32,3: | 1 |
